That's a first-timer! My guess is that Graphviz fonts are somehow missing in your installation / OS. What OS are you on? How did you install Graphviz? Can you try on another OS?
You could also try cdk-dia
's (beta) Cytoscape renderer, which should be more OS agnostic.
What OS are you on?
OS: Amazon Linux 2
$ cat /etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
How did you install Graphviz?
Installed with brew.
$ brew install graphviz
$ brew ls
aom expat gdbm gmp isl libffi libtirpc libxdmcp lzo openssl@1.1 shared-mime-info xz
aws-sam-cli fontconfig gdk-pixbuf graphite2 jasper libmpc libtool libxext m4 pango sqlite zlib
binutils freetype gettext graphviz jpeg-turbo libnsl libx11 libxml2 mpdecimal pcre2 unzip zstd
bzip2 fribidi giflib gts krb5 libpng libxau libxrender mpfr pixman util-linux
ca-certificates gcc glib harfbuzz libavif librsvg libxcb linux-headers@5.15 ncurses python@3.10 webp
cairo gd glibc icu4c libedit libtiff libxcrypt lz4 netpbm readline xorgproto
$ dot -V
dot - graphviz version 7.0.6 (20230106.0513)
Can you try on another OS?
Be able to try it on mac os.
Thank you for your answer.
Additional info because I'm also having this error:
Have been trying to run this on an altered Alpine Linux container (dockerfile below, it's a craftCMS container, but is based on Alpine).
Running outside the container on my host machine (macOS) has the text render normally.
Dockerfile:
FROM craftcms/cli:8.0-dev
# Dockerfile we use for the Craft Development Container
# It extends off the CraftCMS CLI container, and creates a user
# that VSCode can use to log in to the contianer with.
# It then runs the ./local_entrypoint.sh file, which will do the initial setup of CraftCMS.
# This process can take upwards of 5 minutes.
COPY ./local_entrypoint.sh /entrypoint.sh
USER root
RUN chmod +x /entrypoint.sh
# Install GraphViz so we can generate the CDK-DIA diagrams
RUN apk add graphviz
# Add a user for executing Development Container commands, etc
RUN echo "Creating development user"
RUN adduser -s /bin/ash -S container_dev www-data
USER www-data
ENTRYPOINT [ "/bin/sh", "/entrypoint.sh" ]
I also had this issue. I debugged by running Graphviz directly to see any errors/warnings:
dot diagram.dot -T png > test.png
I noticed this error towards the top:
Fontconfig error: Cannot load default config file
After some Googling, I found that the font config path was not set in my environment. Running this solved the problem for me:
FONTCONFIG_PATH=/etc/fonts npx cdk-dia <... other args>
You could also solve this by adding export FONTCONFIG_PATH=/etc/fonts
to your Bash profile.
Hope it helps!
As you can see in the image, the resource name is not displayed.
This is a diagram generated by executing
npx cdk-dia
.I am using v1 of cdk.
Please let me know if you need any information.
